<aside> 💡 React is an open-source JavaScript library developed by Facebook for building user interfaces or UI components. It allows developers to create reusable UI elements and efficiently update the user interface in response to changes in data, resulting in a more dynamic and interactive web application. React follows a component-based architecture, making it easy to manage and organize code. Its virtual DOM system optimizes rendering performance, ensuring a smooth and efficient user experience.

What is React?

React is a javascript library for building:

• component-based ui which allows for the creation of reusable ui elements, which makes it easy to manage and organise code.
• reactive ui which allows to efficiently update the user interface in response to changes in data, resulting in a more dynamic and interactive web application
• declarative ui where the developers have to only describe the ui rather than imperatively specifying each step (aka writing code to change the DOM manually) JSX allows a concise representation of UI, and React efficiently updates the DOM to reflect state changes

React’s virtual DOM system optimizes rendering performance, ensuring a smooth and efficient user experience.
